mann. That Zimmermann did not name the animal Castor 

 piloris, but simply called it "Piloris," in a non-technical 

 sense, is evident from his index where it is entered as Piloris, 

 and not as Castor piloris, and from his general method of using 

 names in Cap. Ill of the 'Zoologiae Geographicae.' Besides, 

 in the ' Geographische Geschichte' (II, p. 360) he refers the 

 Rat musque of Rochefort to Mus pilorides Pallas. If the 

 name Mus pilorides given to this animal by Desmarest in 

 1826 is preoccupied by Mus pilorides Pallas, 1786, as seems to 

 be the case, the proper name of the Rat musque, or Piloris, 

 will be Mus desmaresti of Fischer, i&2(),=Megalomys desma- 

 resti (Fischer), or Oryzomys desmaresti (Fischer) for those who 

 believe, with Mr. Forsyth Major, that Megalomys is not 

 separable from Oryzomys. 



II. THE 'GEOGRAPHISCHE GESCHICHTE.' 



During the interval of three years between the publication 

 of the ' Zoologiae Geographical ' and Vol. II of the ' Geograph- 

 ische Geschichte' quite a number of new mammals were 

 indicated in the works of travellers and other non-technical 

 writers to which Zimmermann gave names in his later work. 

 It is also to be noted that he displayed superior astuteness 

 over Erxleben in separating several species not recognized by 

 the latter. His discrimination is further evinced through 

 his treatment of many forms as " Unbestimmtere Arten," 

 which he merely enumerated without either naming or giving 

 them numbers. 



The species newly named or renamed in the present work 

 (all in Vol. II except the last) appear to be the following, in 

 the order of their position in the work. Those at present 

 recognized in nomenclature are indicated by heavy type. 



Bos moschatus (Vol. II, p. 86):=Ovibos moschatus (Zimm.'). 



Cervus muntjak (p. 131) Cervulus muntjak (Zimm.). 



Tapir anta (p. 15 4)= Hippopotamus terrestris Lwn.=Tapirus terres- 



tris (Linn.}. 



Simia madarogaster (p. i76)=Simia maimon Linn. 

 Papio aethiops (p. 180) ?; not Simia aethiops Linn.
